I won!

There's an odd quality to debates with unbelievers. They "succeed" in shielding themselves from Christianity. They put up enough barriers that they "succeed" in walling themselves off from the evidence. They "won". Christians failed to persuade them. 

But it's like someone diagnosed with curable cancer who convinces himself that homeopathic therapy is the way to go. His doctor futilely pleads with him to undergo conventional cancer therapy. But the patient thinks he "won" the argument. 

Yet it's not the doctor who has a personal stake in the outcome. He's not the one with cancer.
